The Prince's Planet, sometimes referred to as the Home Planet, is a planet in the Katamari Series. It is owned by The Prince and he lives here rather than in the Royal Family's castle to build independence.[2] It essentially serves as the options menu in Katamari Damacy, where the player can save their game, change the controls and vibration settings, and adjust the volume. It also has options to view the object collection, with a small description for each item told by the King.
According to information provided in We ♥ Katamari, it is a very private planet. Its size, however, is up for debate. The Prince is fairly large in comparison, and is able to walk around the entire planet in mere seconds, but the same conditions apply to Earth as well.

The Prince's Asteroid
In Katamari Amore and I Love Katamari, the Prince's Planet is called The Prince's Asteroid and has similar uses like the Prince's Planet. Players can check the leaderboards, time attack records, check trophies through the Game Center and view a photo album to check the collection. There is a shop planet that allows people to buy the different game stories and another planet to learn about more Namco names.
Appearance[]
The planet is a green sphere with a house on top. There is a tree to view the collection, a bird to control the sounds and vibration, a present box where the player can change their accessories, and there is a phonograph to listen to music.

Trivia[]
- In We ♥ Katamari, the planet makes brief appearances in both the intro and the credits minigame. For the latter, it shows up if the player can successfully avoid the King's Sun katamari until the end, where the player flees into the house at the top. This doesn't stop the King, though, so the player is still rolled into the katamari.
- The planet makes another appearance in Beautiful Katamari, during the ending minigame.
- In Beautiful Katamari and Katamari Forever, the Prince's Planet along with the Space Mushroom are located next to the Black Hole.
- If the player idles in Katamari Damacy, the Prince will begin to wander southwards around his planet.
- The Prince and his planet may be a reference to the book The Little Prince.
- In Hoshino Family Travel Diary - Episode 8: Space Travel, Tomino Hoshino states: "It's a planet called Prince's Planet. A small green insect about five centimeters long was discovered there by a space exploration team."[3]
